LFE (Lisp Flavoured Erlang) is very much alive with a whole bunch of new stuff now released on the master branch. For example you can now easily write LFE shell scripts and run them, much in them way as with sh. There is also a good webpage, the http://lfe.io/ you mention, and a growing set of libraries which have been done by me.

There is also a mailing list at https://groups.google.com/forum/?hl=en#!forum/lisp-flavoured... and an IRC chat at #erlang-lisp.

P.S. I also have a prolog running on erlang as well.
